Sanding Drum for a Thickness Sander

Introduction: Sanding Drum for a Thickness Sander

I decided that I wanted to build a Thickness Sander so that I can sand boards that have been glued together for segmented wood turnings. When you have multiple species of wood at different angles, you can't run them through a planner anymore.

This is one of those projects thats great to look at and probably great to use too, however the process of construction is not the way some people would attempt this, each to their own. As with everything there are different ways of solving the problems encountered. The solutions depend on experience and those around to help you. My experience of Techshop is that they overlay complicate and approach a simple solution with the most overly complex and over engineered answers, I learn from those.

Lafnbear -- Good Question -- I was going to go that route until I realized that the drum and rollers are affixed to a 1" and 3/4" shaft respectively. The drum needs to turn at 1725 RPM. There is no way to glue the shaft to a 38" hole that would have had to have been bored through solid wood.

The MDF ( it could have been plywood too) is glued at every point along the set of MDF disks. There is also a great deal of friction holding each disk on to the shafts. It was very difficult to press a 3/4" thick disk onto a shaft when I was ramming more than 2. More than five was a "tactical error" -- I actually had to cut some of them off and start again.

I can't imagine how many tons of pressure I would have needed to get a tight fit if I had turned a 38"+ length of wood. bored a hole, then added glue and tried to push a 1" steel rod through it.
